Application filed January 11, 1909. Serial No. 471,826.

To all whom it may concern:

Be it known that I, ALFRED J. Bronx, a citizen of the United States,residing at St. Johnsbury, in the county of Caledonia and State ofVermont, have invented certain new and useful Improvements in Molding-Machines; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in cement block presses andcomprehends the production of a press capable of being utilized for themanufacture of different sized and different shaped cement blocks or forthe manufacture of brick.

One of the objects of the invention is the provision of a cement blockpress with simple and eilicient mechanism for raising the mold carrierwith a simple and efficient mechanism for withdrawing the block core.

.Another object of the invention is the production of a cement blockpress having sliding tamper mechanism and springs for elevating saidmechanism.

A still further object of the invention is the production of a cementblock press having an adjustable mold carrier and mechanism foroperating the mold carrier.

A still further object of the invention is the production of a cementblock press having a slidable tamper and a detachable tamper platearranged to be locked thereto.

' With these and other objects in view, the.

invention consists of certain novel features of construction,combination and arrange ment of parts as will be fully described andparticularly pointed out in the appended claims.

Figure 1 is a front elevation; Fig. 2 is a central longitudinal section,with certain parts shown in elevation; Fig. 3 is a side elevation; Fig.4 is a transverse section, certain parts being omitted; Fig. 5 is a planview; Fig. 6 is a horizontal section on line 6-6 of Fig. 1; Fig. 7 is aperspective view of the mold carrier; Fig. 8 is a perspective view of amodified form of tamper plate; and Fig. 9 is a longitudinal sectionshowing a modified form of mold and tamper plate.

In the accompanying drawings which are prepared for illustrativepurposes only and thereforenot drawn to scale, numerals 1 and 2designate side standards and 3 a platform which is mounted on saidstandards. A

cross bar 1 connects the upper ends of the standards 1 and 2 and isformed with a series of openings 5 through which a plurality of springsare adapted .to extend. The standards 1 and 2 are provided with guideways 6 and 7 which are adapted to receive V-shaped slides. A secondcross bar 8 is adjustably connected to the front sides of the standards1 and 2 by means of slotted plates 9 which are secured by bolts 10 tosaid standards. The platform 3 is formed U with openings 11 and 12through which'operating links are arranged to move and a central opening13 through which a mold core slidably moves.

A front shaft 14 is journaled in bearings 15 arranged on the standards 1and 2 which are formed slightly wider at their ends than at their upperportions. The shaft 14: is connected by means of an arm 16 to anoperating lever 17 which is preferably arranged on the right side of thepress and on its opposite end is connected to a crank arm 18 havingconnections with an upwardly extending link 19. A weight 17 is securedto the lever 17 A pair of crank arms 20 and 21 are mounted on the shaft14 and connect with links 22 and 23 which extend upwardly throughopenings 11 and 12 in the platform 3. The upper ends of the links 22 and23 are connected by means of bolts 24 with V-shaped slides 25 and 26which move in the guide ways 6 and 7 formed on the standards 1 and 2.The slides 25 and 26 are provided with downwardly projecting hooks 27and 28 and carry a mold carrier 29 which is secured thereto by means ofsaid hooks. The link 19 connects with a link rod 30 which extendsupwardly and is pivotally connected with a crank arm 31 which is mountedon the outer left end of the upper shaft 32 journaled in bearings 33 onthe upper ends of the standards 1 and 2. p

A core operating shaft 34. extends across the lower part of thestandards 1 and 2 through suitable bearings arranged thereon and isprovided on its outer right end with a lever 35 which is keyed theretoand with intermediate crank arms 36 and 37 which are pivotally connectedwith upwardly extending core engaging links 38 and 39. The links 38 and39 pivotallyconnect with a block 4:0 on opposite sides thereof and asuitable core 41 is mounted on said block and adapted to extend throughthe opening 13 formed in the platform 3.

A U-shaped brace 42 is mounted on the upper cross bar 4 and a pluralityof springs 43 extend downwardly therefrom through the openings 5 formedin the bar 4. The lower ends of the springs 43 are connected to a tamper44 which is adapted to slidably move in the guide ways 6 and 7. \Veights44 are arranged on the tamper 44. The tamper carrier 44 is provided withan upwardly extending lock plate 45 which is adapted to be locked by aspring lock or latch 46 which is centrally positioned on the cross bar8.

The tamper carrier 44 is arovided with a removable tamper plate 4 whichplate is locked thereto by means of a locking hook or pin 48 formed onsaid plate and a locking device 49 arranged on the tamper carrier 44.The locking device 49 is provided with a finger engaging hook 50 and adetachably secured protective plate 51 secured to the base of saidtamper carrier. The upper shaft 32 is provided with downwardlyprojecting crank arms 52 and 53 which are arranged, respectively,adjacent to the standards l and 2, and which carry block arms 54 and 55formed with slots 56 through .which adjusting bolts 57 and 58 extend andconnect with the crank arms 52 and 53. The lower ends of the block arms54 and 55 are adapted to engage the operating part of the war movementof said carrier.

The adjustable mold carrier 29 comprises a pair of U-shaped longitudinalside pieces 59 and 60 which are formed with reinforcing ribs 61 and havetheir bent ends formed with bolt holes through which adjusting bolts areadapted to extend. The longitudinal side pieces 59 and 60 are connectedto end pieces 62 and 63 which are formed with end slots 64 and 65 andsaid side pieces are formed with a series of spaced apertures 66 and 67.A pair of hooks 68 are connected to the ends of the longitudinal sidepiece 60 and chains 69 are connected to the ends of the longitudinalside piece 59. The end pieces 62 and 63 are connected with the slides 25and 26 by means of bolts 70 and 71. A mold 72 is adapted to be carriedby the mold carrier 29. The mold 72 is secured on the mold carrier 29 bymeans of eye-bolts 73 and 74 which extend through the openings 66 and 67formed in the longitudinal side pieces 60 and 59 and are connectedtogether by the chains 69. The bolts may be operated to tighten thechains and cause the side pieces to grip the sides of the mold. hen itis desired to adjust the mold carrier 29 for receiving a different sizedmold, the longitudinal pieces 59 and 60 are adjusted on the end pieces62 and 63 and the chains 69 are adjusted on the hooks 68. The chains 69tend to prevent any spreading apart of the mold carrier should the boltsthat connect the lever 16.

tamper carrier 44 and tend to limit the upthe end pieces to thelongitudinal side pieces become loosened.

To operate my improved cement block press. a pallet board 75 is placedon the platform 3 and the mold carrier 29 and the mold arranged thereonis brought to position over the pallet board. In the starting of theoperation of making a cement block, the tamper 44 is connected to thelocking device 46 and the tamper plate 47 is connected to the lockingdevice 48 and both the tamper plate and the carrier are thereby held inan elevated position above the mold. Concrete is then placed in the moldover and around the core 41 and when the mold has been filled withconcrete the tamper plate 47 is released from the mold carrier and bymeans of the lock releasing hook 50 and the tamper carrier 44 is movedon the standards 1 and 2 against the concrete contained in the mold. \Vhen the concrete has been sultieiently tamped, the tamper 44 is heldthereon, in order to prevent the same from losing its shape and theblock arms 54 and 55 are engaged with said tamper to hold the same inits position. The lever 35 is then depressed so as to bring the core 41out of the mold and the mold elevated by the depression of \Vhen themold has been elevated above the concrete block the block arms 54 and 55are swung out of engage ment with the tamper carrier and the tampercarrier 44 brought into engagement with the lock 46, after which theconcrete block may be removed. The block arms 54 and 55 tend to preventthe tamper carrier 44 from rising by means of the springs 43 on thestandards 1 and 2 and the locking plate 45 becoming locked with thelocking device 46. lVhen the lever 17 is depressed, the upper shaft 82will be turned so that said block arms will be swung forwardly therebyenabling the tamper carrier 44 to rise beyond the lower ends of saidblock arms and the locking plate 45 to become locked with the lockingdevice 46.

In Fig. 8, I have illustrated a modification of my improved machinewhereby the same may be employed for making brick instead of makingcement blocks. In this figure, the numeral 76 designates a tampercarrier provided with a plurality of individual tampers 77 which areadapted to enter brick cells formed in a brick mold 7 8 which is carriedby the mold carrier 29 in the way that the cement block mold 7 2 iscarried.

In Fig. 9, I have illustrated another modification of my improvedmachine comprising a tamper plate 79 which is provided with a pluralityof downwardly projecting division plates 80 which are adapted to dividethe cement in the mold 72 into four equal parts for the purpose ofmaking quarter sized blocks.

My improved machine has been found to be very eficient in making twoconcrete blocks in a single operation and with the use of power a largernumber can be made in a single operation.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the invention,will be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportions and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claims.

Having thus described and ascertained the nature of my invention, what Iclaim as new and desire to secure by Letters-Patent is:
